The filthier the music you listen to, the dirtier the ears get, so keep "em fresh and clean with the washable ear cushions and headband of the UrbanEars Humlan Headphones. Just pop the soft parts off and toss them in the wash--that"s it. The Humlan also comes with a Zoundplug, which allows a friend to plug their headphones into yours so you can listen to the same jams, and an in-line microphone and remote so you can pick up calls and control your tunes without digging through your pockets.
